The present research deals with the comparison of the two methods for the determination of vitamin C (ascorbic acid) content in some fruits namely apples, oranges, lemons, tangerines and grapes. The fruits were collected from local market in Baljurashi city. Vitamin C content of fresh fruit were determined by titrimetric and spectrophotometric methods using potassium permenganate as a chromogenic reagent. The absorbance is measured spectrophotometrically at 530 nm. The titrimetric method was carried out by an iodimetric back-titration. The results obtained from this study revealed that there is no significant difference between the two methods, but the spectroscophotometric method has been preferred to determine the amount of vitamin C than the titrimetric method.
